DETAILED DESCRIPTION

Simple Network Management protocol (SNMP) is an application layer protocol used for managing different devices present in a computer network. “SNMP Trap” is a type of information that is commonly used by devices to indicate faults associated with them. Each Trap includes an indicator (such as unique values or error codes) of a specific fault related to a corresponding device. Details related to such indicator is present in Management Information Bases (MIBs) related to the corresponding device. Therefore, in order to understand complete details related to a fault, identifiers carried by the Traps are first extracted, and then details related to such identifiers is looked in corresponding MIBs. A person having technical expertise in understanding the Traps is often required to refer to such MIBs to understand meaning of the identifiers carried by the fault and report such fault, i.e. network alarm, and to manually assign attributes to the network alarm. The network alarm is then addressed based on assigned attributes.

The MIBs related to corresponding devices are different for each devices. Further, the MIBs may also differ for similar devices provided by different vendors. For example, an MIB for a first router belonging to one vendor would be different from an MIB for a second router belonging to another vendor, while the second router has a similar capability and functioning as the first router. Therefore, in practice, the number of MIBs increase to a large number when multiple devices are present in a computer network, and especially when the devices belong to multiple vendors. Referring to such large number of MIBs to understand the faults associated with the devices becomes a tedious task which is currently performed by a person having relevant technical expertise. In this manner, a lot of time gets involved in understanding the faults, and sometimes, the faults may be understood wrongly as a result of human error.

A conventional process of mapping and handling network alarms is now described. At first, network alarms may be received and analyzed. In one instance, a network alarm “linkdown” may be received. Details associated with the network alarm “linkDown” may be analyzed to identify corresponding alarm Object Identifier (OID), VarBind names, and VarBind OIDs. VarBinds or “Variable Bindings” indicate alert data included in a network alarm. Such data is encrypted and is contained in a typical key-value pair configuration.

Successively, attributes related to the network alarms may be categorized and configured. For different VarBinds of the network alarm “linkDown,” attributes such as specific problem, severity/priority, probable cause, unique identifier, and enumeration are tagged. Values or details of these attributes are required to be mapped by referring to a relevant description of the VarBinds present in respective MIB s. A person having relevant technical expertise is required to perform the task of collecting values related to the VarBinds, referring to description of the VarBinds, and accordingly populate details related to the attributes.

Post configuring the network alarms, enumeration (ENUM) values are mapped with the network alarms. For different VarBinds, alarm values and ENUM description of the alarm values are populated. Based on the alarm values, priority and severity are assigned to the VarBinds. Different enumeration values may indicate different status of the network alarm enumeration, for example value ‘1’ may indicate critical, ‘3’ may indicate minor, ‘4’ may indicate information, and ‘6’ may indicate clear.

Finally, clearance levels may be mapped to the network alarms. For the network alarm “linkDown”, a clearance of “linkup” may be assigned. Based on such clearance level assigned to the network alarms, a technician will be assigned to address the network alarms, for example the network alarm “linkDown” in current case.

A conventional process of enrichment of a network alarm is now described. Enrichment of an alarm indicates presenting the alarm in a desired format having required details. Initially, a network alarm is received in a raw format. For a network alarm “linkDown”, date and time of occurrence, source, version of SNMP protocol, and several VarBinds along with OIDs and their values are received. Configuration of the network alarm is checked within a network adapter. The network adapter is configured to receive and store the network alarm in a suitable format. Thereupon, the network alarm is enriched so that an end user can understand the information conveyed by the network alarm. Several details such as a host name, source IP address, date, alarm name, alarm type, specific problem, severity, priority, probable cause, unique alarm identifier, alarm clearance, and service impact are mapped based on the information present in the VarBinds. Thus, to provide the necessary details to an end user in an understandable format for addressing the network faults, a detailed understanding of different network domains, alarms objects and parameters is required. Therefore, the process of providing mapping of network alarms in a user understandable format is not only a complicated task but also requires significant efforts.

To address such challenge, current invention provides a system and method for recognizing and addressing network alarms in a computer network. Specifically, a trained data model is used to recognize and address the network alarms arising in the computer network. The trained data model are developed by learning upon multiple network alarms, from multiple devices of multiple vendors, indicating operating conditions of different network devices, and attributes pre-identified to be associated with each of the multiple network alarms.

Initially, a network adapter is configured to receive network alarms related to an operating condition of a network device present in the computer network. Thereupon, information present in the network alarm is analyzed to determine elements indicating the operating condition of the network device. The elements indicating the operating condition of the network device may comprise keywords, object identifiers, and values of the object identifiers. Finally, the trained data model is used to analyze and map the network alarm with standard attributes. The network alarm mapped with the standard attribute conveys a network fault that can be easily understood, and thereupon rectified.

Referring to FIG. 1 , a network connection diagram 100 of a system 102 for recognizing and addressing network alarms in a computer network 104 is explained. The computer network 104 includes network devices such as a network switch 106, a first router 108, a second router 110, and a third router 112. Such network devices 106, 108, 110, and 112 may belong to different vendors and may be configured to transmit network alarms in different formats. The system 102 is connected with the communication network 104 to process network alarms received from the network devices 106, 108, 110, and 112 present in the communication network 104. Although the system 102 is illustrated to be a separate hardware entity connected to the communication network 104, it is possible to implement functionality of the system 102 in one or more routers or switches present in the computer network 104.

The second router 110 is illustrated to be connected with multiple end devices i.e. a desktop computer 114, a Hard Disk Drive (HDD) 116, and a laptop 118. A limited number of network devices and a limited number of end devices are shown to be present in the communication network 104 merely for ease of illustration; however, numerous network devices and end devices would generally be involved in any communication network. The system 102 upon processing the network alarms received from the computer network 104, may provide mapped and enriched network alarms to a display device 120 present at a Network Operation Center (NOC). A manner of processing the network alarms to produce the mapped and enriched network alarms is described in detail in successive paragraphs.

FIG. 2 illustrates a block diagram showing different components of the system 102 for recognizing and addressing network alarms in the computer network 104. The system 102 may comprise a processor 200 and a memory 202. The memory 204 may store program instructions for performing several functions through which network alarms could be recognized and addressed in the computer network 104. A few such program instructions stored in the memory 202 includes program instruction to receive network alarms 204, program instructions to analyze information present in network alarms 206, and program instructions to map objects of network alarms with standard attributes 208. The system 102 may receive several network alarms i.e. alarms 1, alarm 2, alarm 3 . . . alarm N from the network devices 106, 108, 110, and 112, and may process such network alarms using the program instructions 204, 206, and 208.

The program instructions to receive network alarms 204 may cause the processor 200 to receive network alarms, such as Simple Network Management Protocol (SNMP) alarms, from different network devices managed by different vendors. The network alarms may indicate operating conditions of the network devices. The operating condition, for example, may refer to connectivity with other devices, bandwidth available for communication, or temperature of device. The program instructions to analyze information present in network alarms 206 may cause the processor 200 to analyze information present in network alarms to determine elements indicating the operating condition of the network devices. Generally, the elements include keywords, object identifiers, and values of the object identifiers.

The program instructions to map objects of network alarms with standard attributes 208 may cause the processor 200 to map objects included in the network alarms with standard attributes using a trained data model. The trained data model may be developed by learning upon several network alarms indicating operating conditions of several network devices and attributes pre-identified to be associated with each of the several network alarms. When employed on a network alarm, the trained data model may map objects of the network alarm into at least one standard attribute. In case a relevant attribute is not identified to be present already, a new attribute corresponding to the network alarm may be created. Detailed functioning of the program instructions 204, 206, and 208 will become evident upon reading the details provided successively.

FIG. 3 illustrates an exemplary layered architectural diagram 300 of the system 102 for recognizing and addressing network alarms in the computer network 104, in accordance with an embodiment of the present invention. The layered architectural diagram 300 illustrates a fault manager 302 comprising an enrichment engine 304 and a network adapter 306. The network adapter 306 may be configured to receive network alarms from different networks such as mobility (2G/3G/4G/5G) network 308, transmission network 310, Internet Protocol (IP) network 312, and data center 314. Further, the network adapter 306 may be configured to receive the network alarms from multiple network device types belonging to multiple vendors, namely vendor 1 through vendor n.

In an exemplary embodiment, a data model stored in the network adapter 306 may analyze information present in the network alarms with reference to Management Information Bases (MIBs) related to the network alarms. The data model may be developed using suitable machine learning techniques, to learn upon a plurality of network alarms indicating operating conditions of a plurality of network devices and attributes pre-identified to be associated with each of the plurality of network alarms. Upon analysis, the network adapter 306 may map various objects of the network alarms with standard user understandable attributes, such as specific problem, severity, probable cause, and unique alarm identifier. The data model present in the network adapter 306 may also create mapping of enumeration value for specified objects as per MIBs, generates alarm priority mapping and may generate alarm clearance mapping, based on information specified in MIB s. The network adapter 306 may then feed the enrichment engine 304 with the mapping of enumerated values of objects, priority mapping for values received in alarm, and alarm clearance mapping.

The enrichment engine 304 leverages mapping of enumerated values, priority and clearance received from the network adapter 306. The enrichment engine 304 translates/replaces the appropriate values received in the network alarm with corresponding mapping values. The network alarms mapped with corresponding attributes and enriched information is presented to a user at a Network Operation Center (NOC) presenter 316. The NOC presenter 316 displays such information in a real time on dashboards 318. Further, the NOC presenter provides a unified view of the network alarms mapped with corresponding attributes on a unified alarm window 320. Such information may also be forwarded to an incident manager 322 for raising tickets for field engineers to address the network alarms.

Referring now to the flowchart 400 of FIG. 4 , a method of recognizing and addressing network alarms in the computer network 104 is now described. In this regard, each block may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that in some alternative implementations, the functions noted in the blocks may occur out of the order noted in the drawings. For example, two blocks shown in succession in FIG. 4 may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. Any process descriptions or blocks in flow charts should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included within the scope of the example embodiments in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved. In addition, the process descriptions or blocks in flow charts should be understood as representing decisions made by a hardware structure such as a state machine.

At block 402, a network alarm, such as a Simple Network Management Protocol (SNMP) alarm, indicating an operating condition of a network device is collected. In an exemplary scenario, the network alarm may be received from the second router 110. The operating condition, for example, may refer to connectivity with other network devices, bandwidth available for communication, or a temperature of the network device. In one scenario, the network alarm may be received by the network adapter 306, configured to communicate with the network devices 106, 108, 110, and 112 present in the computer network 104.

Successively, information present in the network alarm is analyzed, at block 404. Upon performing analysis of the network alarm, elements indicating the operating condition of the second router 110 are determined. Generally, the elements include keywords, object identifiers, and values of the object identifiers.

At block 406, a trained data model is employed on the network alarm to map objects present in the network alarm with relevant attributes that could be understood by a user. The trained data model may be developed by learning upon several network alarms indicating operating conditions of several network devices and attributes pre-identified to be associated with each of the several network alarms. The attributes may be pre-identified to be associated with each of the several network alarms based on definitions of the elements stored in Management Information Bases (MIBs) corresponding to the several network devices. In this manner, domain knowledge, alarm classification, and mapping approach utilized in previous instances may be used in developing the trained data model.

When employed on the network alarm, the trained data model may map the network alarm into at least one existing attribute. The existing attributes may include, for example, Specific Problem, Severity, Priority, Unique Identifier, Probable Cause, Enumeration value, and Clearance. In case a relevant attribute is not identified to be present already, a new attribute corresponding to the network alarm may be created.

At block 408, the network alarm may be enriched, using mapping of enumerated values, priority, and clearance values. Appropriate values received in the network alarm may be translated/replaced with corresponding mapping values. The network alarm mapped with standard attributes and enriched information may be presented at a Network Operation Center (NOC) in a format that is easily understood by a field engineer. In this manner, the field engineer can understand the details associated with the network alarm and then address the network alarm accordingly.

FIG. 5 a illustrates exemplary instances related to supervised learning technique used by the trained data model. In one case, a network alarm titled as “petTrapTemperaturePredictiveFailureDeasserted” may be received. Keywords present in name of the network alarm may be identified as Trap, Temperature, fail, and Deasserted. Such keywords may be searched in a predefined priority matrix bag of words, and may be ranked based on the classified keywords. Rank of all these keywords may be identified and a highest rank may be selected. Finally, priority of a keyword having a highest rank may be used for assigning priority to the network alarm. In current case, priority of the network alarm may be identified as ‘NA’ Clear based on the priority of the keyword “Deasserted” having the highest rank.

In another case, a network alarm titled as “petTrapTemperaturePredictiveFailureAsserted” may be received. Keywords present in name of the network alarm may be identified as Trap, Temperature, Fail, and Assert. Rank of all these keywords may be identified and a highest rank may be selected. Finally, priority of a keyword having a highest rank may be used for assigning priority to the network alarm. In current case, priority of the network alarm may be identified as ‘P3’ Major based on the priority of the keyword “Asserted” having the highest rank.

As further illustrated in FIG. 5 a , for clearance mapping ‘Clearance Antonym Vector’ may be used. In such case, an alarm clearance bag of words may be maintained on one side, and raise alarm bag of words may be maintained on another side. For clearance mapping, vector relationship may be established between the alarm clearance bag of words and the raise alarm bag of words. For example, a vector relationship may be established between the keywords “Active” and “DeActive”. Further, ENUM values defining priority of a network alarm may also be used for the clearance mapping.

FIG. 5 b illustrates exemplary instances related to unsupervised learning technique used by the trained data model. In one implementation, synonym vector may be utilized by the unsupervised learning technique. Synonyms may be identified for new keywords identified to be associated with the network alarms. For example, as illustrated in FIG. 5 b , a keyword “good” may be identified as a synonym of a keyword “better”. Such newly identified keywords may be added to a bag of words referenced by the trained data model. In certain cases, lemmatization technique may be used to establish relationship with new keywords and define rank for the new keywords.

In one exemplary implementation, a trained data model was developed by learning 800 keywords, 120000 known attributes, and 15000 known network alarm types, belonging to 60 different vendors. Upon implementation of the trained data model on a computer network for identifying network alarms, following accuracy was achieved in mapping of network alarms with the attributes.

S.No. Attribute Accuracy 1. Specific Problem   99% 2. Severity 98.4% 3. Priority 90.4% 4. Probable Cause 99.8% 5. Unique Identifier 97.4% 6. Clearance 90.5%
